New Delhi, Sep 4 (Reporter) Former Principal of Kolkata's RG Kar Medical College and Hospital Sandip Ghosh on Wednesday filed a petition in the Supreme Court against the decision of the Calcutta High Court which ordered a CBI probe into an alleged graft case against him. Ghosh said that the Calcutta HC didn't hear his side before handing over the investigation to the CBI. He also said that High Court made a comment linking the incident of rape in the hospital to corruption unnecessarily. A bench headed by Chief Justice of India DY Chandrachud will hear his plea on September 6. Dr Ghosh is under investigation for alleged corruption and financial irregularities in the RG Kar medical college and hospital. The probe follows a directive from a single bench of the Calcutta High Court, which ordered the Central Bureau of Investigation (CBI) to look into the matter. Ghosh was arrested on Monday in connection with the corruption case. Alongside him, three other suspects – Afsar Ali Khan, Ghosh's security guard; Biplab Singha, the owner of Maa Tara Traders, a vendor for RG Kar and Suman Hazra, a medical shop owner in Howrah accused of selling recycled medicines from the hospital – were also taken into custody. They were all remanded to CBI custody until September 10. The corruption charges come amid the raging case of a post-graduate trainee doctor from the medical college being raped and murdered. On August 24, in compliance with the orders of the Calcutta High Court, the CBI officially registered an FIR against Ghosh in connection with an alleged corruption case. The Indian Medical Association (IMA) of Kolkata also suspended the membership of Sandip Ghosh. Moreover, the CBI revealed that Ghosh was allegedly part of a "bigger nexus." Ghosh faced public outrage, including physical assaults both inside and outside the courtroom. The CBI has charged the four under Section 7, Prevention of Corruption Act (for accepting illegal gratification by a government servant) Section 13 Clause 2 of the Prevention of Corruption Act (public servant committing criminal misconduct), Section 420 IPC, (cheating), Section 409 IPC (criminal breach of trust), ection 120B, criminal conspiracy and Section 467 IPC (forgery of a document) among others...////...
